Claims

[Scope of Claim for Utility Model Registration] In a printed board to be inserted into a printed board connector, a taper with a rising angle of about 30 degrees in the board thickness direction is formed from the tip end face of the printed board plug, and the plug is A printed board characterized in that the intersection of the surface of the conductor portion and the taper is a curved surface with a radius of curvature of approximately 1 mm.
